That is really cool! I'm assuming the torque is phenomenal? What is the power delivery like, smooth or abrupt?

As much as it pains me to say this, I'm actually looking forward to seeing the progression of the E market. I'm thinking a stripped down MX bike or a DH MTB on steroids. Saw one recently that I thought was really cool, the Alta. And then they were gone!
WE have not tested it yet

Need more stuff like this. I see all these Emtb guys and Im just thinking "put a twist throttle on that thing already, you guys aren't fooling anyone with the pedal assist bs"

Little update we finished the bike.
weight: 255 lbs but it feels way lighter than that when moving it around.Feels lighter than my ktm.
I have a lot of tuning but as of now it feels like a 125 but with more power down low.

Hi' I want want to show you guys a project I have been working on with my brother,
2010 Rmz 450 converted to electric. The goal is to have around 43 hp.
And this is not the number that will be on the bike!

I dont know how DM . Id like to know some specifics if ya don't mind on the motor and battery types you used. Thinking about doing this to a KX100 big wheel frame.

Changed a couple settings today and its alot faster now I almost looped out on the street.
All tracks are closed because of winter so can't fully test the bike but here is a start I did today.

That almost looked a little bit slow, then I realized that the back tire never actually got much traction at all. Just a little bit of rolling on the throttle to let the rear hook up and it looks like that could be a rocket!

Sick. Have you though about an e-clutch? On a 125 you hold it wide open and govern power with the clutch. And if it bogs you fan the clutch. Given an e-bike is controlled entirely by the throttle, and the controller is mapped. Well even if you didn’t delve into the controller mapping you could build a seperate unit to combine clutch and throttle inputs electronically. Whiskey throttle is an issue. Ask Doug Henry. There is more control of power with finger grip than wrist twist. And if you DID delve into the controller mapping. Well.

So how much do you think you have into the conversion money wise?

@rivvs great work man. This thing is badass. I'd be really interested to know all the electrical components you used. I've been really interested in starting an electric project for a while and it seems like there are good options available now to do it.

It the first time I ride an electric bike and I am hooked! It so much fun. In the video I could not get any traction it dug around 5 inches deep rut all the way! Considering the e-clutch I don't think it needs it I can map the trhottle and the engine to get the best setting etc. The it is settup now It hit very hard maybe i will need to detune it a bit.
For the cost I have around 5000 to 6000 canadian dollar invested (including the price of the bike itself)

You keep bringing up kV, but that’s the abbreviation for kilovolts (kv or kV). The unit you’re looking for is Kv.

spode.

Ask Ronnie Renner about whiskey throttle on the Alta. I personally would want a clutch just for that time that shit goes sideways. It does happen and even if I never used the clutch any other time, I’d want it just for that one time things go south.

Holy crap! I saw that Ronnie Renner whiskey clip the other day. Scary deal.

rivvs that RMZ is really cool.

The motor is from a chinese company. Looking around online I have seen good review about it but I havent seen people who used it for motocross riding more like enduro. So we will try it.

And considering the countershaft if there is a problem we can always build another version.

What Controller did you use for this build? Also would it be possible to flip the motor around and do away with the jackshaft?

ASI controller
Yes it would be possible but then you have the sprocket far from the swingarm and you eed to get a custom made rear sprocket to have the correct reduction.

...or just paint a realistic looking kickstarter on the side!

I would love to put that motor in a YSR50! On second thought...

So I know nothing, and only dream of one day doing something like this to my YSR 50. Your work looks outstanding! Nicely done!

In my "fantasy Yamaha future e-bike" design, and as an outsider who knows nothing... it's too bad that down spar near the front can't be pushed towards the front wheel a little more. In my imagination, the battery box becomes a battery "fit wherever it can" to get the weight as far down as possible, in line with the wheels as much as able. I imagine that one could get separate cells, wire them together, and have them fit wherever they can, making a custom "box" with the weight in front of the motor as much as possible, with whatever doesn't fit in front of the motor, is above it.

I can see that blocking the air to the motor more too... I am no expert. We'll wait for the major manufacturers to come out with their 9th year models to see how refined they'll get.

Nice work! Thanks for sharing.

Where did you source the battery? Did you build it yourself? How are you charging it? Looks damn good!

I built the battery myself inspired from the battery design of tesla.
Bac 8000 the 4000 wouldhave been too slow.

Did you use 18650's for batteries? Are you running the bms on charge only? Or are you regulating on discharge too? I am part way thru a very similar build. I am also running a gear reduction shaft as I am not too keen on the oversized rear sprockets necessary to get the correct ratio for the electric motors without the clutch reduction on an ICE bike. It just takes some time to source which parts and then fitting them together. Looks great, after watching your video, I can't wait to get mine to spinning.

What battery's are you using and how many parallel and series.

18650 cells and bms only for charging.
